I see the same behavior on my MacBook Pro.

I spoke with Apple a couple times, and they were able to reproduce  
the problem with tcpdump on an Intel machine. They confirmed it's a  
bug, but said they "don't support command-line utilities", and  
finished off saying that they may or may not investigate it further.

So is there a solution for running wireshark without dropping the  
connection? I realize this isn't a wireshark problem, pre se, but is  
there a workaround anyone has had luck with?
